Harrison went on to say that "children were involved," but later said he could not confirm that children were among those killed or injured.

"To find that children were involved, people were involved, you know, multiple people, we're working to get the answers to all of that, but what we can say, it really rattles everybody," Harrison said. "That's why you see us all out here."

Harrison pleaded with the public to come forward with any information they might have. Crimestoppers quickly doubled its normal reward for information that leads to an arrest or conviction.

The initial report came through shortly before 5 a.m. Friday morning. The incident took place in the 4200 block of Touro Street.
